Abstract

A paper sheet feeding device for sequentially feeding, to a conveyance path, mail items simultaneously received includes a suction mechanism provided adjacent to a pickup position. The suction mechanism includes a chamber having an opening opposed to the pickup position, a guide plate provided at the opening of the chamber, and two projections vertically arranged on the surface of the guide plate. When air is drawn from the pickup position through a plurality of suction holes formed in the guide plate, the leading one of the mail items closest to the pickup position is drawn to the pickup position, and is curved between the two projections. A handling nozzle blows air into the space that is formed between the leading mail item and a subsequent mail item when the leading mail item is curved.
